I just tried this new quest, and I got dupicates of the Hench group that I took.
I had two of each - myself and 2 x 3 henchies.
i also think that the Chaos Rifts are spawning in duplicate. Not sure if this is supposed to be like this.

I think it's supposed to be that way! Imagine how hard it would be to do those missions with just three lvl 3 hench....... I had a hard enough time in a party of 4 lvl 20s doing those 2 :P
